in the latest chapter it showed that Orochimaru knew how to release the sole from the death reaper's belly
so why the f@#k he didn't do it before?
when third hokage performed the jutsu, Orochimaru didn't knew about it and it was 3 years ago
so why didn't he released his hand's sole before(he got consumed by Sasuke)
(I am pretty sure he learned about releasing the sole from death reaper after his hand's sole got sealed and before he got consumed by Sasuke because after he got consumed he didn't had a chance to do research about the jutsu)
SO WHY OH WHY?
is Kishi pissing us more?
